Hate NATs as much as you want. Blame them for keeping state in the network
or whatever you want. But don't don't blame them for making flawed design
evident.

FTP PORT does not work in the presence of an ipv6 diode firewall, either.
And layer 3 addrs in layer 7 protocols is not clean design. Period.
